Aircraft head-mounted visualization system with hasps compatible with audio headphones

Abstract

Visualization systems are provided which are intended to be worn by the head of a user wearing an audio headset consisting of a first hoop and two lateral earpieces, the visualization system comprising at least one headband in the form of a strap and a visualization device mounted on the headband. The headband comprises two symmetrical lateral hasps, each hasp being in the form of an arch so as to form an opening of a few centimeters between the arch and the head of the user so that, when the system is worn by the head, the opening is sufficient to allow the passage of one of the two lateral arms of the first hoop.

The invention claimed is: 
     
       1. A visualization system intended to be worn by the head of a user wearing an audio headset consisting of a first hoop and two lateral earpieces, said visualization system comprising at least one headband in the form of a strap and a visualization device mounted on said headband, wherein said headband comprises two symmetrical lateral hasps, each hasp being in the form of an arch so as to provide an opening of a few centimeters between said arch and the head of the user so that, when the visualization system is worn by said head of the user, said opening is sufficient to allow the passage of each one of the two lateral arms of the first hoop. 
     
     
       2. The visualization system as claimed in  claim 1 , wherein the headband comprises a second head hoop that can be adjusted in length. 
     
     
       3. The visualization system as claimed in  claim 1 , wherein the headband comprises a nape brace that can be adjusted in length. 
     
     
       4. The visualization system as claimed in  claim 1 , wherein the visualization device comprises an optical module comprising a display, a collimation optic and a thin optical plate for superimposing images. 
     
     
       5. The visualization system as claimed in  claim 4 , wherein the visualization device comprises a posture detection assembly fixed on to the optical module. 
     
     
       6. The visualization system as claimed in  claim 5 , wherein the posture detection assembly is hybrid and comprises an optical recognition system and an inertial sensor. 
     
     
       7. The visualization system as claimed in  claim 1 , wherein the headband comprises means for translating and rotating the visualization device, said rotation means comprising an articulated pivot or ball joint. 
     
     
       8. The visualization system as claimed in  claim 7 , wherein the visualization device has a first position of use in which a thin optical plate is disposed in front of an eye of the user and a second, set-aside position, said second position being substantially perpendicular to the first position, the optical plate being disposed level with the forehead of the user in this second position.
